I've got a guy in town who for a nominal fee (big surprise) has fun with mandrel bends, he's the same one who did my exhaust. The IC tubes are 3" and I believe the intake is as well. I've also got a C&L 76mm MAF (36lb cal) installed.

still more

Did it help the performance???

[plev72]

even more

little bit more

look closely ;-)

last one... oversized aluminum radiator ... precludes me from getting a double IC I think :-( Damn thing still runs hot! (stupid fan!)

[plev72]

Well, keeping in mind that I don't have a baseline for this particular car... and it was my first time driving anything at the strip... my times stunk. Both in terms of 0-60 (high 2s) 1/4 mile (15.3-15.8) and speed (@75-88?? mph). I've got underdrive and 10% pulley on so I'm getting much too much boost and even running around 94/95 octane I was hitting 14/15+ pounds of boost and after a few seconds the computer would told back off and I'd lose power (thus the lousy @mph times) It looks like the tube to the throttle body may have come loose after the first run, which would explain some of the problems. My supercharger still seems to be running fairly well, so I will probably pull off the 10% pulley and try again... I would expect much better times if I can keep the computer from retarding the spark... I had been hoping for at least mid 14s if not very low 14s...

As far as the heat goes, the radiator touching the IC is a no-no. An IC fan is in order too.

That is very cool looking. I had plans of doing that about 2 and a half years ago, but no money...and then i wrecked the SC. Are you going to wrap the tubes with the header insulation wrap? It would probably cut down on head even more.

[plev72]

I was wondering if IC fans actually made enough difference to make the investment worthwhile? As for the clearance between the IC and the radiator, unfortunately there wasn't any which is how it ended up this way. Apparently the Radiator fit the space exactly with no room to spare. :-(

I've been wondering the same thing about my IC fan. I've forgotten to turn it on a few times and didn't seem to do any better when I did turn it back on. It's really hard to tell if it's really effective or not. I suspect in many cases maybe not. Maybe I should have it blow thru the front instead of pulling from behind? If you make a double IC it won't be any bigger side to side, only front to back. Shorten up the tubes a bit?

[Joey OKC]

I suspect that it really makes a difference depending on the weather in your area. It made a difference on my SC here in OKC. It pulled a little harder from about a 20mph roll. I think it may have been because at that low speed, there isn't much aif flow through the IC and with the fan, there was a constant air between the baffles.

Paul,

Your problem may not be related to the larger pipes, but the location of your MAF. Many people that have the MAC (brand) intake have problems with the signal from the MAF because of the placement of the MAF just after or before a bend. Try rotating the MAF about 90 deg from the original position.
